What fahrad is this 16volt cap? I have an idea that it is 10 micro-farad/uF.
And the positive is the side with + right?

Nice.... 😀 Thanks. I had an idea that I read it right, I just wanted to make shure as I am a bit insecure when it does not explicitly say "uF".

A better question would be what other type of capacitor, aside from Tantalum, can you replace these capacitors with for the same original specification.

Plan your life wisely, you'll be dead before you know it.

Modern monolithic ceramic capacitors are superior to tantalum in almost every way, including lower ESR.

These would do the trick...

General advice:

ceramic caps can sometimes, not always, replace tantalum.. Ceramic caps work somewhat differently.

Modern electrolytics, however, can essentially always replace tantalum. Tantalum caps are specialized electrolytics.

Yes, I always ramble this much.

These kind of caps tend not ever needed replaced, but I guess it better to replace them than it is to have them fail and take the card with it.

Sure, there are still a few cases where the use of a tantalum dielectric may be warranted, but besides those few fringe use cases tantalum capacitors have been essentially made obsolete by monolithic ceramics.

When it comes to decoupling, as the tantalum parts are obviously used for in the OP's picture, there's no question some 10uf MLCC ceramics would perform the job just fine.

Honestly, in 95% of cases, these caps are used for local decoupling. Honestly any cap will get the job done here.

It is a mistake to think you can solve any major problems just with potatoes.
